d.Is destroyed by refrigeration
Explanation
Salmonella Typhi lives only in humans and is spread when an infected food handler contaminates food, often via ready-to-eat items and beverages. It is one of the Big 6. Refrigeration does not destroy it, and it clearly affects humans, causing typhoid fever.
